“…The photo detector can be a photo transistor, a reverse-biased LED, or a Light Detect Resistor (LDR). The light captured by the photo transistor which acts as a sensor, passes the output to the comparator which compares the binary input, and similarly the original image is recovered using Matlab software in the PC, see Figure 5 [8,9].…”

Communication by light or VLC by its acronym in English (Visible Light Communication), uses visible light from light emitting diodes (LEDs) to transmit information. Using a computing device and some hardware, the transmission of information is performed driving and modulating the light emitted by the LEDs. In the receiver side, the information carried by the modulated light is demodulated through a photo-detector, which is usually connected to a similar computing device for the final recovering of the information. In this article we describe an application based on VLC using OOK (On-Off Keying) modulation, to transmit and receive a line of text and an image from a RaspBerry Pi computer (using Python as the programming language), and several modules (LEDs and a sensor light) from LittleBits.

“…The two-stage access point of selection for hybrid visible light communication (VLC) and radio frequency(RF) networks using fuzzy logic carried out was by considering different required data rates; some users attached to the VLC and the remaining ones assigned to RF [6]. Integrated Li-Fi smart communication through illumination presented by authors [7] was on data transmission between two devices. Data was modulated and sent to LEDs on the transmitter part while photodetector receives it, demodulates and decodes it.…”

Network performance is the measure of the quality of service offered by the network. It hinders when multiple loads are running on a wireless local area network, thereby causing slow down in social communication, networking, and business activities. This paper aimed at improving network performance in a wireless local area network using light fidelity technology. The light fidelity system designed and developed was a bidirectional system of downlink and uplink transceiver circuits. Physical measurement was carried out on the developed light fidelity system using Netlimiter software to capture the network performance. Results obtained showed that the performance of light fidelity systems throughput was high, while the latency and packet loss was low. The network performance of the light fidelity system was better than the wireless fidelity technology in the wireless local area network. Its network performance is not significantly affected by the number of users and hence should be utilized in a high-density environment. ). temperature, low cost, small size, and long lifetime [11]. Photodiodes operate as photodetectors, tomography, smoke detectors, and blood gas monitors.Light Fidelity is safe and used in areas where RF communication cannot fit in, such as aircraft, underwater, and hospital without causing interference [7]. In aviation, it cannot interfere with the pilot's navigation systems and as well provide high-speed internet using the overhead bulb present in the airplane. Even in underwater applications, it could replace wires used in underwater remotely operated vehicles with a high powered lamp or headlamps for communication and data processing. Li-Fi can be used to control the medical equipment and avoid any of it being hazardous to the patient's health [12]. Li-Fi cannot penetrate the walls because of its shorter wavelength, but it is a potential candidate for mobile connectivity yielding higher data rates and higher security. III. MATERIALS AND METHODBidirectional communication for the Li-Fi system involves uplink and downlink transceiver circuits. In the design of the downlink Li-Fi transceiver circuit, the characteristic impedance of LAN output taken as 100ohms is in line with the standard norm of IEEE. At the transmitter side, 28 pins ML4664 single-chip integrated circuit LED driver shown in fig. 1 was used to obtain superior performance and avoid system complexity. ML4664 is an LED driver that converts 10BASE-T Copper media to 10BASE -F Fiber media and offers a current output that directly drives an LED.

In today's world where information security is one of the real concern, it winds up essential to get new strategies for the information transmission. Visible Light Communication (VLC) is rising as new strategy for information transmission in which information is transmitted through LEDs. This is a considerably more secure technique for transmission contrasted with existing innovations. Likewise the information transmission rate is high around few GBps. The utilization of different shaded LEDs can deliver distinctive velocities and information rates. This paper portrays the plan of Li-Fi sound transmission framework and investigating its execution.
